CHURN.

Specification of Letters Patent.

Patented March 6, 1906.

Application filed flctchsr 28, 1985. Serial No. 284,861.

To all whom, it may concern:

Be it known that I, JAMES D. FonsY'rI-I, a citizen of the United States, residing at Springfield, Illinois, have invented certain new and useful Improvements in (horns, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use my said invention.

My invention relates to churns of that class which have rapidly-reciprocatin jars or other vessels contaming the cream w ich is to be churned.

The purposes of my invention are to provide a churn having jars which are oppositely reciprocahle, to provide improved means for retaining the jars on the machine, and to provide improved means for imparting the reciprocating movement to the jars;

With these ends in view my invention consists in the novel features of construction and combinations of parts shown in the annex d drawings, to which reference is hereby macfe, and hereinafter particularly described, and finally recited in the claims.

Referring to the drawings, in which similar reference-numerals designate like arts in the several views, Figure 1 is a side e ovation of the complete machine. Fig. 2 is an end elevation, and 3 is a horizontal section on the line 3 3 of Fig. 1.

Uprights 1 are secured in a vertical position on 81118 2. Cross-pieces 3 connect the uprights 1, and braces 4 connect the uprights with the sills 2. Rods 5 ass through and slide freely in holes in this cross-pieces 3. Platforms 6 are firmly secured to the rods 5. J are 7 rest in recesses on the platforms 6, and the recesses in the platforms prevent accidental displacement of the jars. The jars 7 have screw-caps 8, such as are in common use on fruit-jars. Plates 9 have on their under side recesses 9", in which fit s rings 10, which also fit around the ca s 8. he lates 9 are pierced by holes, in W 'ch the re s 5 fit, and the plates are detachably connected with the rods by set-screws 11 or equivalent connecting devices so arranged that the plates may be quickly andconveniently moved upward or downward on the rods 5 and secured in position to accommodate jars of different sizes,

When the jars are in position on the platforms 6, the springs surround the caps 8 and the upper ends of the s rings rest in the recesses 9 A shaft 12, iaving opposite cranks 13, turns in suitable bearingson the uprights 1. A fly-wheel 15 is secured on the shaft 12. Connecting-rods 14 connect the cranks 13 with the plates 9. A cog-pinion 16 is secured on the shaft 12. A bracket 19 is secured alongside one of the uprights 1. A short shaft 18 turns in holes in the upright 1 and the bracket 19. A cog-wheel 17, secured on the shaft 18, meshes with and drives the inion 16. A crank 20 is secured on the she t 18. v

The operation of the device is as follows: The cans being partially filled with cream and the caps 8 being screwed thereon, the caps are inserted in the springs 10 and the jars are pushed upward suificiently to permit the bottom of the jars to enter the recesses in the platforms 6, and the sprin s serve to re tain the jars in position on t e platforms. The crank being turned turns the wheel 17, which drives the pinion 16, thereby turning the shaft 12, so as to cause the rapid reciprocation of the platforms 6 through the instrumentality of the cranks 13, the connectingrods 14, and the lates 9, and the reciprocating movement of the platforms agitates the cream in the jars, so as to quic y produce butter.

Having fully described my invention, what I claim as new, and desire to secure by Lettors Patent, is

1. A churn comprisin sills, vertical uprights secured on said silFs, braces secured to said sills, a bracket on one of said uprights, a shaft tnrningin said bracket and the adjacent upri ht, a co -wheel and a crank secured on said s aft, a ouble crank-shaft turning in hearings on the uprights, a fly-wheel on the crank-shaft, a inlon on the crank-shaft meshing with sai cog-wheel, cross-pieces connecting said uprights, parallel rods sliding in holes in said cross-pieces, platforms secured to said rods, plates detachably connected with said rods above said jars, springs acting to hold said jars in position on said platforms and connecting-rods connecting said cranks with said plates, as set forth.
